Atall flagpole is a harmonic oscillator, flexing back and forth with a steady period. the pole rises from a base that is fixed in the ground, but you can push it forward from chest height. to increase the amplitude of the pole's motion, you should push it forward when it isa. moving toward you.
b. as close to you as possible.
c. moving away from you.
d. as far from you as possible.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
